Hi Iain and all, I grow a couple species of Brodiaea outdoors in a raised bed rock garden here in USDA zone 5, central Indiana. The weather is better here at the moment than yours is, but I'll still defer going outdoors to hunt for the appropriate markers until the wind and rain go away, if you don't mind. I think they are B. californica and B. coronaria, but I need to check. They seem to have been hardy year round outdoors, at least so far. They grow in summer and disappear below ground in winter. I've been growing B. pallida inside my cool greenhouse, since it wants to grow in winter. If I put some of the pallida outdoors, they might very well decide they wanted to grow in summer.
